add single-click, double-click and long-press events

It would be awesome to have 3 types of events that could be used, similar to AWS IoT Button
This way we could assign more actions and instead of 3 devices we could use one 🙂

The way this works is that it restarts the board whenever you click the button, so sadly that wouldn't work without making it consume way more power.

@Merlin04 there is an option to detect a double-click using, for example, this code. I'm not sure about long-press.
AWS IOT button battery lasts about 2000 clicks (see FAQ), so I guess they have an option to save the battery somehow.
